South African tax education

Tax Case Studies for Individuals

These educational case studies show how small differences in facts can change a South African tax outcome.

Last updated: 19 May 2026

Key takeaways
  • Match every tax decision to the correct tax year and source documents.
  • Check SARS pre-populated data against your own records before filing.
  • Get advice where cross-border income, disputes, business income, or material claims are involved.

Case study 1: The employee who accepted too quickly

Lerato receives an auto-assessment and almost accepts it immediately. Before doing so, she checks her medical aid certificate and finds that one dependent was missing from the pre-populated data. She reviews the return instead of assuming SARS has everything.

Lesson: auto-assessment still needs taxpayer review.

Case study 2: The side-hustle freelancer

Andre earns a salary but also invoices clients on weekends. His employer deducts PAYE from salary, but no tax is withheld from freelance income. He keeps invoices, expenses, and bank records, then checks whether provisional tax applies.

Lesson: PAYE on salary does not cover every separate income stream.

Case study 3: The rental property owner

Naledi rents out a flat. She keeps lease agreements, bank statements, levy statements, repairs invoices, and bond interest records. At filing, she separates capital improvements from ordinary rental expenses.

Lesson: rental income needs clean records and careful expense classification.

Case study 4: The South African abroad

Michael works overseas and assumes he no longer has South African tax obligations. He later discovers that residency status, foreign employment income rules, and South African-source income still need review.

Lesson: cross-border tax depends on facts, records, and treaty position.

What these cases have in common

  • The correct answer depends on documents.
  • Timing and tax year matter.
  • Pre-populated data should be checked.
  • Advice is useful when facts cross categories.
